The fixed guide groove cam structure 20 is mainly used for positioning the driving part 10, so that the driving part 10 moves along the fixed guide groove 21 arranged on the fixed guide groove cam structure 20, and general movement tracks comprise an elliptical track, a fluctuating movement track and the like; in the present embodiment, the driving member 10 moves circularly along the track of the fixed guide slot 21 provided on the fixed guide slot cam structure 20, and in the present embodiment, the moving track of the driving member 10 can be changed by only changing the fixed guide slot 21 provided on the fixed guide slot cam structure 20.
To illustrate the above technical effects, as shown in fig. 1, 2, 3, and 4, the driving member 10 further includes:
a driving shaft 11 is arranged at the position of a central point where diagonals of the fixed guide groove cam structure 20 intersect; the drive shaft 11 serves as a drive output means of the drive member 10 for transmitting power; for driving the crank arm 12; one end of a crank arm 12 is fixedly connected to one end of the drive shaft 11; a waist-shaped groove 13 is arranged on the crank arm 12 along the axis of the crank arm 12; the crank arm 12 is used for driving the driven mechanism to circularly move along the track of a fixed guide groove 21 arranged on a fixed guide groove cam structure 20; the waist-shaped groove 13 drives the sliding block 14 to move, so that a device for limiting the movement track is formed. Therefore, one end of the sliding block 14 passes through the waist-shaped groove 13 and is movably connected with the fixed guide groove 21;
and a driving gear 15 fixedly coupled to the other end of the driving shaft 11, such that the driving gear 15 drives the driving shaft 11, and then the driving shaft 11 drives the driving crank arm 12 to rotate, and the slider 14 makes a desired movement path because the slider 14 is disposed in the kidney-shaped groove 13 and is restricted to move along the path of the fixed guide groove 21.
In order to illustrate the above technical effects, as shown in fig. 1, 2, 3, and 4, the fixed guide groove cam structure 20 further includes:
a fixed base plate 22 is fixed below the fixed guide slot cam structure 20;
a vertical plate 23 is fixedly connected above the fixed bottom plate 22;
a fixed guide groove 21 is formed in the vertical plate 23 along the periphery of the vertical plate 23;
the above-described structure will be explained with reference to the position structure of the fixed guide groove 21 on the fixed guide groove cam structure 20.
Meanwhile, a fixed block 24 is arranged on the inner side of the fixed guide groove 21, and the driving shaft 11 penetrates through the center position of the fixed block 24; holes are arranged on the periphery of the driving shaft 11 on the fixing block 24; the fixed block 24 is fixed to the slider 14 via the crank arm 12. The above-described structure can secure the positional relationship between the fixed block 24 and the crank arm 12 and the slider 14.
To illustrate the above technical effects, as shown in fig. 1, 2, 3, and 4, the fixed guide groove 21 is disposed around the fixed block 24 along a predetermined track. The shape of the fixed guide slot 21 is arranged to follow the trajectory of the object driven by the crank-slider cam mechanism. In the present embodiment, the fixed guide slot 21 has any one of a square structure and an oval structure, and the slider 14 can realize an undulating motion track or an up-and-down undulating motion track.
To illustrate the above technical effects, as shown in fig. 1, 2, 3, and 4, the length of the kidney groove 13 in the present embodiment is equal to or greater than the running radius of the fixed guide groove 21. The length of the waist-shaped groove 13 is at least more than half of the length of the crank arm 12. Meanwhile, the crank arm 13 in the present embodiment makes a circular motion around the drive shaft 11; the drive shaft 11 is coaxially connected to the crank arm 13.
